tries to send mail on port 25—and it gets blocked.
The solution? Choose a different port. From the Home screen, tap SettingsÆMail,
Contacts, Calendars. Tap the name of your POP account.
Scroll down to the Outgoing Mail Server. Tap the address there to edit it.
Finally, tap On to open the SMTP screen.
At the bottom of this screen, you’ll find the Server Port box. Change it to
say 587.
Try sending mail again. If it’s still not sending, try changing that Server
Port to 465.
• Use AT&T’s mail server. When you’re home, your computer is connected
directly, via cable modem or DSL, to the Internet provider’s
network. It knows you and trusts you.
But when you’re out and about, using AT&T’s cellular network (Chapter
6), your Internet provider doesn’t recognize you. Your email is originating
outside your ISP’s network—and it gets blocked. For all the ISP knows,
you’re a spammer.
Your ISP may have a special mail-server address that’s just for people to
use while they’re traveling. But the simpler solution may just be to use
AT&T’s own mail-server address.
Once again, from the Home screen, tap SettingsÆMail, Contacts, Calendars.
Tap the name of your POP account. Scroll down to the Outgoing
Mail Server. Tap the address there to edit it.
Here, you’ll discover that the iPhone 2.0 software lets you set up backup
mail-server addresses. If the first one is blocked or down, the iPhone will
automatically try the next one in the list.
You’ll notice that the AT&T SMTP server should be listed here already. (If
you tap it, you find out that its actual address is cwmx.com, which, at one
time, stood for Cingular Wireless Mail Exchange.)
If you’re like thousands of people, that simple change means you can
now send messages when you’re on AT&T’s network, and not just receive
them.
If you’re having trouble connecting to your company’s Exchange mail, see Chapter
15.
